Features
Autoswitching — The YCS SW2 A can be configured to
automatically switch to the active input when the YCS
detects a signal, thus providing hands-free switching.
If both the composite video and the S-video signals are
present, the switcher defaults to input 2, S-video.
Digital encoding and decoding — The YCS SW2 A digitally
decodes (separates) the composite video input signal into
Y and C for S-video, and encodes (combines) the Y and C
signals of S-video input into composite video.
Audio — The YCS SW2 A features a 2x1 switcher for unbalanced
stereo audio.
Digital time base correction — Time base correction stabilizes
the video signal in the time domain. This results in a
significantly more stable image on the screen and better
recording quality from input sources with unstable video
signals, such as consumer VCRs and worn or multi-
generation VHS tapes.
Simultaneous composite video and S-video outputs — One
composite video and one S-video output allow for
recording and display at the same time.
Contact closure remote control — Inputs can be selected
remotely with a user-supplied contact closure device.
Quad standard compatibility — The digital quad standard
decoder/encoder provides for universal compatibility.
Enclosure — The YCS SW2 A has a compact 1U high, ¼-rack
wide, 3 inches deep Versatools
®
metal enclosure that can
be easily placed or mounted in a variety of locations.
Power supply — An external 12 VDC power supply with a
two-pin captive screw connector accepts 100 to 240 VAC.
Rack and furniture mounting — The YCS SW2 A can be
mounted on a rack shelf, under a desk or podium, or on a
projector pole, with an optional mounting kit.
About this Manual
This manual describes the Extron YCS SW2 A Switcher, and
discusses how to install, configure, and operate it.
The terms “YCS SW2 A,” “YCS,” and “Switcher” are used
interchangeably throughout this manual.
About the YCS SW2 A
The Extron YCS SW2 A is a high-performance, two input,
dual output video and audio switcher with transcoding and
autoswitching capabilities and digital time base correction
(TBC).
The YCS SW2 A has one composite video and one S-video input,
which can be switched and transcoded to output simultaneously
on a composite and an S-video output. Each input also has
an unbalanced stereo audio input switched to one unbalanced
stereo audio output.
Using a 3-line NTSC/5-line PAL digital comb filter, the YCS
accepts NTSC 3.58, NTSC 4.43, PAL, or SECAM composite
video, and decodes the signal into Y (luma) and C (chroma) for
S-video. As an encoder, it combines Y and C signals and outputs
a composite video image.
You can select inputs by pressing the front panel buttons, by
enabling autoswitching using a jumper wire, or by contact
closure using a remote push-button device.
Certain projectors have both video and S-video inputs, but
can use only one of them at a time. Because of this, they
usually share one audio input between them. The YCS SW2 A
solves this problem by allowing both an S-video source and a
composite video source, each with audio, to be connected to
this type of projector, and switch between them automatically.
The remaining video output can then be used for monitoring
or recording purposes. (See figure 1-1 under “Application
Diagrams,” later in this chapter.)
The YCS SW2 A can also be used at the output of a multi-format
switcher, such as the Extron MPS 112, to automatically select
between the video and S-video group outputs, sending a single
S-video signal to the projector. (See figure 1-2.)

UL rack mounting requirements
The following Underwriters Laboratories (UL) requirements
pertain to the safe installation of the equipment in a rack.
1. Elevated operating ambient temperature — If the
equipment is installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the
rack environment may be greater than room ambient
temperature. Therefore, install the equipment in an
environment compatible with the maximum ambient
temperature (Tma = +113 °F, +45 °C) specified by Extron.
2. Reduced air flow — Install the equipment in a rack so that
the amount of air flow required for safe operation of the
equipment is not compromised.
3. Mechanical loading — Mount the equipment in the rack so
that a hazardous condition is not achieved due to uneven
mechanical loading.
4. Circuit overloading — Connect the equipment to
the supply circuit and consider the effect that circuit
overloading might have on overcurrent protection and
supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this
concern.

Wiring the Power Connector
If using a different external power supply from the one provided
with the YCS, you may need to wire the connector for it.
To wire the power connector,
1. Cut the DC output cord to the length needed.
2. Strip the jacket to expose 3/16 inch (5 mm) of the
conductors.
C
Exposing more than 3/16” (5 mm) of the copper
wires could allow the stripped wires to touch each
other, causing a short circuit. This could result in
the external DC power supply overheating and/or
burning.
Stripping the wires to expose less than the
recommended amount may cause them to slide out
of the connector too easily, even if they are tightly
pinched by the captive screws.
3. Slide the leads into the supplied 2-pin captive screw plug
and secure them, using an Extron Tweeker or other small
screwdriver.
4. To verify the power cord’s polarity before connecting
it, plug in the power supply with no load and check the
output with a voltmeter.
The figure on the next page shows how to wire the connector.

3. Insert the ends of the second wire into pin holes 2 and 3 of
the captive screw plug, connecting pins 2 and (3).
4. Use an Extron Tweeker or other small screwdriver to
tighten the plug’s three screws, so that the wire ends
remain securely in place.

Wiring the Captive Screw Connector
The 3-pin, 3.5 mm captive screw connector is used for optional
remote contact closure control of the YCS SW2 A and/or to
enable autoswitching between inputs connected to the YCS.

Contact Closure
Pins 1, 2, and (ground) of the captive screw connector enable
input switching via a latching contact closure device. If you
want to select inputs remotely, you can connect a momentary
contact closure device to pins 1, 2, and of the rear panel
captive screw connector.
Momentarily short pin 1 to to select input 1; momentarily
short pin 2 to to select input 2.
N
If the contact closure inputs remain latched, front panel
input switching is disabled.
Autoswitching
You can set up the YCS to automatically select the active,
connected input. If both inputs are active, selection defaults to
input 2 (S-video). Autoswitching remains in effect as long as the
jumper wires are connecting the three pins together.
When autoswitching is in effect, the green Auto Switch LED on
the front panel lights, and the front panel input selection buttons
are disabled.
To enable autoswitching,
1. Cut two small pieces of wire to use as jumpers.
2. Insert the ends of one wire into pin holes 1 and 2 of the
provided 3-pin captive screw plug, connecting pins 1 and 2
together as shown in figure 2-14, on the next page.

Enabling Black and White Mode for NTSC
In order to detect NTSC signals that are black and white only,
the YCS must be placed in black and white mode. To enable this
mode, use the small jumper that is provided within the unit.
The jumper temporarily connects two pins on the YCS internal
board. To make this connection, fit the jumper onto the two pins
(“closed” position). To break the connection, remove the jumper
from one of the pins (“open” position).
To use the jumper to enable black and white mode,
1. Remove power from the YCS.
2. Using an Extron Tweeker or other small screwdriver,
remove the four case screws on the sides of the unit.
3. Gently slide the top cover up and away from the lower
housing.
4. When you open the YCS, the jumper is attached to one of
two pins on the internal board, located behind the front
panel buttons (open position). “JMP1” is printed on the
board, to the left of the pins.
Lift the jumper off the pin and carefully slide it onto the
two pins, so that both pins are inserted in the jumper’s two
sleeves (closed position).

When placing the jumper on the two pins, make
sure that the fine wire connecting the two sleeves
is at the top (outside). Do not attempt to force the
pins through the wire.
5. Replace the case cover onto the YCS and secure it with the
four screws that you removed in step 2.
N
When the YCS SW2 A is in NTSC black and white
mode, it does not process PAL N and SECAM signals.
